January 6, 2021 Board Meeting IV. Special Reports: Phalen Creek Daylighting Detailed Feasibility Study

DATE: TO: FROM: RE:

December 24, 2020 CRWD Board of Managers Elizabeth Hosch, Permit Program Manager Phalen Creek Daylighting Detailed Feasibility Study

Background In early 2019, the Board reviewed the Phalen Creek Corridor Study completed by Lower Phalen Creek Project and Interfluve. This study was jointly funded by CRWD and Ramsey-Washington Metro Watershed District and began the ongoing work to daylight the historic creek channel between Lake Phalen and the Mississippi River. This type of work falls under the CRWD’s goal of “Bringing Water Back”. The Phalen Creek Corridor is ranked high in the District’s Stream Corridor Restoration Plan (adopted in 2010) for all three evaluation factors (Opportunity Rating, Constructability, and District Goals). The corridor is also included in the recently adopted 2020 Watershed Management Plan.

In late 2019, CRWD initiated the next step in the daylighting assessment to coincide with Ramsey County’s Rush Line Bus Rapid Transit project as initial design got underway. The Rush Line BRT project runs along a portion of Phalen Blvd making this ideal timing to complete two projects at once and co-locate stream daylighting with required stormwater practices. HTPO was hired as the consulting firm to complete this work and provide additional design recommendations stemming from the initial feasibility study. CRWD coordinated with community and agency partners throughout 2020 to solicit input for the design recommendations and continue cooperation towards our shared goals.

Issues HTPO has completed the Phalen daylighting design recommendations and compiled the results in a technical memo. This memo is enclosed and HTPO will be at the Board meeting to present the study to the Managers.

Phalen Creek Daylighting Improvements Detailed Feasibility and Design Recommendations Technical Memorandum

Introduction and Background Consistent with CRWD’s 2010 Watershed Management Plan and Stream Corridor Restoration section and the “Bring Water Back” to Saint Paul initiative, this document continues the efforts begun by Lower Phalen Creek Project (LPCP) to create a daylighted creek within the historic path of Phalen Creek. Alongside this goal, HTPO was tasked with providing both a technical assessment and design recommendations for daylighting options along Phalen Boulevard in Saint Paul.

Figure 1 outlines the extent of the proposed Phalen Creek route connecting Lake Phalen to the Mississippi River, this document’s Reach 5 and 6 Focus Area, and subsequent upstream Reaches.

The historic path of Phalen Creek is, at present, woven through a corridor comprised of residential neighborhoods, multi-modal transitways, light-industrial and commercial lots, and once-geologically rich landscapes. Lake Phalen and Phalen Creek, including Swede Hollow, are areas of cultural and geological significance, particularly to the Dakota communities of Saint Paul.

Considering the diversity of present-day user groups, land use, and community needs in the area, daylighting Phalen Creek presents complex technical strategies and design opportunities that we approach in this document. Our scope had to be sensitive to existing projects and uses, including the Rush Line Bus Rapid Transit project, the Bruce Vento Regional Trail, Phalen Boulevard, and adjacent greenway spaces. In this pursuit, we have conducted a technical review of the existing and proposed context, built-upon findings previously presented in the Inter-Fluve technical memorandum and feedback from community engagement events, while creatively thinking through strategies to interweave stormwater and a daylighted creek channel.

Our Focus Area recommendations concentrate primarily on Reach 5 and 6 between Neid Lane and Frank Street, with specific consideration for upstream connections in Reach 6 and 7, and an integrated stormwater approach with the Rush Line BRT project. We reviewed Rush Line BRT’s potential stormwater needs and how both near- and long-term connections with the daylighted Phalen Creek could be implemented. Due to differing timeframes, funding, and project scopes, these connections can provide opportunities as the Rush Line BRT project and Phalen Creek Daylighting projects progress alongside one another.

Stakeholders and Project Partners HTPO worked alongside several stakeholders and project partners on this project, including Capitol Region Watershed District (CRWD), the Rush Line Bus Rapid Transit (Rush Line BRT) preliminary design team, Ramsey County, City of Saint Paul, Lower Phalen Creek Project (LPCP), and the Payne-Phalen District Council, for development, input, and review of this technical memorandum.

Phalen Creek Daylighting Improvements Detailed Feasibility and Design Recommendations Technical Memorandum

Considerations Existing Conditions As outlined in Inter-Fluve's Technical Memorandum, Attachment D, the current land uses in the vicinity of the proposed daylighted Phalen Creek alignment runs through a number of varying existing conditions. This data was originally collected by Inter-Fluve from a number of project partners including the City of Saint Paul, Minnesota GeoSpatial Commons, Capitol Region Watershed District (CRWD), and the Ramsey Washington Metro Watershed District (RWMWD).

The Bruce Vento Regional Trail and other recreational attractions in the area contribute to frequent visitor traffic by car, foot, and bicycle. At present, much of the effected corridor land area is controlled by Ramsey County and the City of Saint Paul.

The proposed Phalen Creek alignment through Reaches 5, 6, and 7 is situated between varying expanses of park, retail, commercial, industrial/utility, and mixed-use residential land. The soils are generally sandy loam within the Reach 5 Focus Area and silty loam within Reach 6 and 7, however overall, they are highly disturbed urban soils. The Reach 5 Focus Area is the most developed area of the corridor, consisting of impervious surfaces, industrial and commercial development, and overlapping utility networks. Upstream, in Reaches 6 and 7, the majority of adjacent land is designated as undeveloped, with mixed use residential areas existing nearer the proposed alignment. At the south end of Lake Phalen, the Metropolitan Council Environmental Services’ (MCES) sanitary sewer interceptor runs within the Reach 7 area, and the Phalen Creek Tunnel runs along the proposed Phalen Creek alignment for the majority of the Reach 5 and 6 Focus Area. These existing conditions create a technically complex intersection of an urban transit corridor with a proposed daylighted creek channel.

Soils Investigation Per Braun Intertec’s preliminary environmental assessment for the Rush Line BRT project, initial findings concluded that a number of lots along the corridor are in restrictive covenant areas where soil contamination is likely. A map of the proposed Rush Line BRT soil boring locations and restrictive covenant areas is attached in Attachment F. It is recommended that further testing, soils investigation, and analysis specifically supporting the daylighted creek channel design be conducted. Further confirmation of existing conditions and exploration of jurisdictional status of proposed work impacts on wetlands, daylighted creek channels, and stormwater Best Management Practices (BMP) will be necessary for the implementation of detailed stormwater design and daylighted creek conveyance.

Future Project Implications – Rush Line BRT The Rush Line BRT corridor that has been established intersects the Phalen Creek Daylighting project corridor along Phalen Boulevard. Our design recommendations for creek conveyance methods and adjacent programming opportunities take into account the Rush Line BRT’s current alignment for roadway and trail development. Our recommendations and findings are based on these preliminary plans, and therefore do not supply details as it relates to Rush Line BRT’s project scope, extents, and proposed locations.

Based on these preliminary plans, shown in Attachment E, we have developed near- and long-term strategies for creek daylighting and propose a combined pipe system in conjunction with the Rush Line BRT project. The expected timeline for construction of the Rush Line BRT is between 2024 and 2026.

Due to varying project timelines between Rush Line BRT and the Phalen Creek daylighting project, as well as funding constraints, a near-term solution can be considered to coincide with the Rush Line BRT timeline.

Phalen Creek Daylighting Improvements Detailed Feasibility and Design Recommendations Technical Memorandum

Community Engagement Ongoing community outreach, engagement, and feedback events continue within this corridor. As part of Lower Phalen Creek Project’s (LPCP) 2018 Feasibility Study, numerous engagement events in 2017 and 2018 found strong localcommunity support for daylighting Phalen Creek. In particular, participants identified the daylighted creek within Reach 7 and a portion of Reach 5, that aligns with the preliminary Rush Line BRT route, as most preferred. The most recent engagement event conducted in the Fall of 2020 is summarized in Attachment B. Attendees surveyed at this event provided positive feedback for a restored Phalen Creek within this corridor and appreciated learning more about the Creek’s history and cultural connection to the Dakota at this event.

Overall, respondents favored the benefits resulting from daylighting Phalen Creek with a preference for "A more natural ecology and wildlife habitat." Highlighted in Attachment A, we suggest a number of design opportunities that combine programming and water treatment to strengthen the natural habitat and ecology connections. Providing such opportunities along the corridor would ensure community engagement and appreciation would continue well beyond the formal outreach efforts of the project.

Opportunities, Constraints, and Recommendations We have chosen to structure this document by sub-reach area, breaking down the intricacies of this extensive corridor and highlighting both the opportunities and constraints for future planning and development. Starting in this document’s Focus Area, the portion of Reach 5 and 6 between Neid Lane and Frank Street (Figure 2) and working upstream through Reach 6 (Figure 11) and Reach 7 (Figure 12) towards Lake Phalen, we outline what we consider the opportunities of these reaches and sub-reaches, the spatial and technical considerations, and design recommendations for an integrated stormwater and daylighted creek channel solution. In this document, we reference the Reach 5 subreach label order as identified in Figure 2 and Tables 1 and 2 of Inter-Fluve’s Technical Memorandum in lieu of the subreach label order depicted in their Appendices’ maps (refer to Attachment D).

Reach 5 Focus Area, Sub-reach E: Neid Lane to Arcade Street The approximate 6-acre land area of Reach 5, Sub-reach E, is currently owned by City of Saint Paul, Saint Paul Public Works, and Ramsey County Regional Railroad Authority, and is currently predominately open green-space comprised of clustered volunteer trees and native and non-native herbaceous grassland plant cover. There is an existing City of Saint Paul basin and constructed wetland at the southwest corner of the site, providing stormwater management for a portion of Neid Lane’s impervious surface. The Bruce Vento Regional Trail bisects the open space providing a trail connection to Phalen Boulevard. Figure 3 below illustrates these conditions along with the Rush Line BRT route, potential stormwater BMP as well as stormwater design recommendation strategies further described herein.

* Example imagery of select opportunities are illustrated in the Attachment A matrix.

Reach 5 Focus Area, Sub-reach E: Design Recommendations Based on the compiled base map information in Attachment C and site opportunities and constraints above, at Arcade Street we recommend that the path of Phalen Creek be daylighted as it continues to follow the Bruce Vento Regional Trail toward the Neid Lane underpass. The route of the creek channel could follow the existing low point within the existing site topography as shown in the Figure 4 cross-section below. The proposed creek channel section, included from Inter-Fluve’s Technical Memorandum, has a 4-ft bottom with 4:1 (horizontal: vertical) side slope tie ins. With an overall channel length of approximately 700-ft and 10-ft of grade change between the channel bottom near Neid Lane underpass and the daylighted pipe at Arcade Street, the overall channel grade is 1 to 2%. With this grade along the channel length, the channel could step with riffles, pools, and runs at key intervals to provide opportunities to mimic natural stream water flow characteristics.

Figure 4 – Proposed Reach 5, Sub-reach E Cross Section 1

8

Phalen Creek Daylighting Improvements Detailed Feasibility and Design Recommendations Technical Memorandum This creek channel could be designed and constructed to receive Rush Line BRT’s pretreated stormwater flows conveyed through a combined pipe from Reach 5, Sub-reaches D-A. This channel would appear as a seasonal, dry creek bed during non-storm events in the near-term condition until the Reach 6 Phalen Creek pipe is connected into the system. Once connected, the creek channel would have a base flow of 1 cfs per recommendations in Inter-Fluve’s Technical Memorandum, which would equate to approximately a 2-inch flow depth at a 1% grade.

As shown in Table 1, the stormwater volume requirement of the Rush Line BRT stormwater BMP in this area is estimated to be around 11,000 cubic feet (based on the 1.1-inch CRWD treatment volume requirement). Based on available open space, topography, and existing infrastructure, the proposed open channel could be designed to handle up to 14,000 cubic feet of pretreated stormwater volume, based on a channel with an average 20-ft width by 700-ft length, with approximately ten 1-foot depth stepped pools. This additional capacity potential presents an opportunity to further evaluate, outside of this document, other sources of stormwater that could be directed to this area for improved water quality or rate control purposes.

Volume Potential requirement (cu ft) volume (cu ft) No proposed impact 11,000 11,000 14,000

Existing City Basin/Constructed Wetland Potential Rush Line BRT Proposed open, stepped channel

Prior to the Neid Lane overpass, we suggest that this combined water channel (Rush Line BRT stormwater and Phalen daylighted creek) outlet into a diversion structure which would direct all discharges into the existing Phalen Tunnel until the creek channel is constructed downstream of Neid Lane. This diversion structure would also provide opportunity for peak flow management during storm events, diverting the 1 cfs base flow to the daylighted creek channel downstream of Neid Lane in the future.

Based on Braun’s preliminary environmental work there is potential soil contamination in this area, as shown in the restricted covenant maps in Attachment F. If verified, design considerations such as an iron-enhanced soil filtration media, a liner, and/or a drain tile network will require further exploration to mitigate water infiltration into or from the contaminated areas.

Reach 5 Focus Area, Sub-reaches D - A: Arcade Street to Earl Street In this area, open greenspace is currently limited and will be further condensed once Rush Line BRT is constructed, as illustrated in Figures 5-8 of this section. Current land uses adjacent to the corridor are predominately industrial and mixed commercial. With the construction of the Rush Line BRT and realigned Bruce Vento Regional Trail, remaining open space will be primarily on these adjacent private properties.

•

Public open space is limited once BRT is constructed. Future land redevelopment and/or acquisition will be necessary to provide adequate space for a daylighted creek.

Potential soil contamination may impact stormwater and creek channel system design

* Example imagery of select opportunities are illustrated in the Attachment B matrix.

Reach 5 Focus Area, Sub-reaches D-A: Design Recommendations NEAR-TERM STRATEGIES In the near-term, the creek flow in this portion of Reach 5 would continue through a piped conveyance, as there is presently limited land available for a daylighted creek without impacting private properties as shown in Figure 5 and Cross Section 2, Figure 7 and Cross Section 3, Figure 8.

Based on a 1 cfs base flow, it is recommended that the Rush Line BRT’s storm sewer pipe network be sized to accommodate this additional future base flow rather than constructing separate pipe systems. This appears to be the most cost effective and timely partnership potential by designing and constructing this portion of the system as part of the Rush Line BRT project. However, this combined pipe approach would require Rush Line BRT’s stormwater to be appropriately pretreated prior to entering the combined underground pipe network. This could include a combination of pretreatment measures such as sediment collection structures and green infrastructure components.

To make this combined pipe network functional for future, long-term redevelopment opportunities, two diversion structures, located at Earl Street and Forest Street, could be incorporated into the Rush Line BRT’s system design at this time but kept offline until private property partnership or future redevelopment and creek daylighting could occur.

Perceptible green infrastructure measures (refer to Attachment A) such as permeable trail pavements, bioswales within the Bruce Vento Regional Trail boulevard, and/or linear rain gardens at key intersection nodes could be utilized to visually connect between the stepped pool east of Earl Street and the open channel west of Arcade Street. Natural stone materials and strategic native plantings representing a dry creek bed could be strategically installed throughout the corridor to imply the connectivity to water.

Phalen Creek Daylighting Improvements Detailed Feasibility and Design Recommendations Technical Memorandum

Figure 5 – Proposed Reach 5, Sub-reaches D-A Plan: Near Term Strategy, Arcade Street to Earl Street

LONG-TERM STRATEGIES In the long-term, daylighting the creek within this portion of Reach 5, as shown in Figure 6 is a possibility but would require redevelopment, existing property owner partnership, and/or land acquisition of adjacent industrial lots. In this scenario, the two off-line diversion structures installed in the near-term strategy could be brought online, diverting the underground combined pipe flows or a portion thereof to an open channel daylighted creek bed. These diversion structures provide future options for redevelopment and creek daylighting phasing within this two-block stretch.

Once redevelopment, partnerships, and/or land acquisitions can be realized, the opportunity exists to explore updates to existing older developments that do not meet CRWD stormwater treatment goals by connecting their pretreated stormwater to the open daylighted channel.

In addition, based on Braun’s preliminary environmental work there is potential soil contamination in the area between Forest Street and Earl Street, as shown in the restricted covenant maps in Attachment F. If verified, daylighted creek channel design considerations such as a liner and/or a drain tile network will require further exploration to mitigate water infiltration into or from the contaminated areas.

11

Phalen Creek Daylighting Improvements Detailed Feasibility and Design Recommendations Technical Memorandum Based on preliminary Rush Line BRT profile grades, existing adjacent development topography and the daylighted pipe elevation at Earl Street, a minimum of an additional 40- to 50-ft of right-of-way or easement would be required to construct the daylighted creek channel assuming a 4-ft channel bottom and 4:1 side-slopes to tie into existing grade, as shown in Cross Section 2, Figure 7. Less right-of-way or easement would be necessary where steeper side-slopes and/or retaining walls were designed at pinch points, as illustrated in Cross Section 3, Figure 8.

Reach 6 Focus Area: Portion from Earl Street to Frank Street The land area adjacent Reach 6 between Earl Street and Frank Street, is owned by City of Saint Paul and is bounded by residences to the North and street right-of-way to the West, South, and East. In this portion of our Focus Area, the creek flow is proposed to be channeled through an underground piped conveyance due to existing grade and pipe elevation constraints as identified in Inter-Fluve’s Technical Memorandum. Figure 9 illustrates this section of Reach 6, the Rush Line BRT route and potential stormwater BMP as well as stormwater design recommendation strategies further described herein.

* Example imagery of select opportunities are illustrated in the Attachment A matrix.

Reach 6 Focus Area: Design Recommendations There is one existing City stormwater basin as well as one potential Rush Line BRT stormwater BMP identified within this area. Their respective BMP volume capacities along with potential treatment volume in cubic feet (cu ft) is summarized below in Table 2.

Table 2 - Reach 6 Focus Area Stormwater BMP Treatment Volumes

Volume requirement (cu ft) 6,000 (estimated) 5,900 11,900

Existing City Basin Potential Rush Line BRT Proposed Stepped Pool, combination option

Potential volume (cu ft)

13,500

A linear, slightly meandering stepped pool system, as shown in Figure 10, is recommended to manage Rush Line BRT’s stormwater and retain the existing City of Saint Paul basin within this Reach that receives stormwater from Phalen Boulevard. The existing basin’s design predates CRWD’s stormwater requirements and so we assume by combining these facilities there would be water-quality benefits for the district beyond the Rush Line BRT project.

We foresee the stepped pool acting as a dry channel during non-storm events. This stepped pool’s preliminary design, as shown in Figure 10, is comprised of approximately 20 connected shallow pools, stepped at 1-ft depth intervals which run the length of the block. Pools range in width between 15-ft and 25-ft but could be widened to approximately 50-ft wide near each end to reach the overall potential volume of 13,500 cubic feet as noted in the above table. All storm flow would outlet into a diversion structure which would split flow between the proposed combined pipe system of the near-term strategy and the daylighted open channel option west of Earl Street in the long-term strategy.

Based on Braun’s preliminary environmental work there is potential soil contamination in this area, as shown in the restricted covenant maps in Attachment F. If verified, design considerations such as an iron-enhanced soil filtration media, a liner, and/or a drain tile network will require further exploration to mitigate water infiltration into or from the contaminated areas.

Reach 6: Portion from Frank Street to Magnolia Avenue East Directly upstream of this document’s Reach 5 and 6 Focus Area, is the remainder of Reach 6 as shown in Figure 11. The length of this reach sits along the transit corridor of Phalen Boulevard and the proposed Rush Line BRT, with adjacent land use being comprised primarily of parkway greenspace, park, a yard waste facility, and residential lots. Along this stretch, Reach 6 acts as a critical transition and connection corridor between Reaches 5 and 7.

One wetland, a Freshwater Pond per the Minnesota Department of Natural Resources classification, was identified within Reach 6 and is located on Ramsey County property. This property currently is operated as a yard waste collection site. At the time of our site visit, the wetland was not visible from public right-of way due to an existing fence and woody vegetation buffer. At this time, it is not anticipated that there will be impacts to this property and wetland as a result of this project. Additional exploration should be conducted to verify the jurisdictional status, and if future work will in any way impact this existing wetland.

We concur with the findings of Inter-Fluve’s Technical Memorandum that the 1 cfs base creek flow be conveyed via an underground pipe due to spatial constraints, depth of excavation, and ground plane elevation in this area. This existing grade and depth to pipe is further illustrated in Attachment C’s plan and profile graphics. Construction of this pipe, in conjunction with the Rush Line BRT project, would be most cost effective if its final design, funding, and construction was completed within the 2024-2026 Rush Line BRT timeframe.

Rush Line BRT’s preliminary plans identify two potential BMP’s within this Reach, to meet the required treatment volume estimated at about 1,800 and 1,600 cubic feet, respectively. While available space exists for these treatment measures, our recommendation is to consider these stormwater treatment measures as a series of linear, connected basins resembling the stepped pool and creek channel designs described earlier herein, to provide visual continuity between Reaches 5, 6, and 7, while the actual base creek flow is conveyed below ground within Reach 6.

Reach 7: Magnolia Avenue East to Wheelock Parkway Reach 7 is located within the Ramsey Washington Metro Watershed District (RWMWD). This land area is owned by City of Saint Paul and is bounded by a residential neighborhood to the west and Johnson Parkway to the east. At present, this area is unprogrammed, however ample open green space holds potential for future uses, such as community gatherings, educational interactions, and naturalized parkland alongside an open stream channel. Figure 12 below depicts the Reach 7 proposed daylighted channel route between Lake Phalen and Magnolia Avenue East.

Figure 12 – Proposed Reach 7 Plan along Johnson and Wheelock Parkway

Phalen Creek Daylighting Improvements Detailed Feasibility and Design Recommendations Technical Memorandum There is an existing MCES sewer interceptor that bisects underneath the existing open space. This utility has a 35-foot wide easement over the pipe alignment, as depicted in the Figure 13 cross section below, which will restrict the proposed creek channel location. In Attachment C, a more detailed base map of the existing utilities and potential channel route to avoid the sewer interceptor is shown.

Figure 13 – Proposed Reach 7 Cross Section 4

The existing topography of Reach 7 would allow for gradual slopes to a daylighted creek channel as illustrated in Figure 13 above. Adding visual interest and connection to the restored waterway in this area would provide for an open, parklike space for visitors to access and investigate the daylighted creek. Here it is possible that the channelized water could be represented through more naturalistic features that promote habitat and creek channel stabilization. For continuity between Reaches, the use of a family of consistent site amenities, wayfinding, and natural stone materials, will create a cohesive visual identity for the corridor. Precedent examples are further illustrated in Attachment A. Further engineering, design analysis, and coordination with the RWMWD will be necessary to construct this open channel and associated control structure at Lake Phalen to complete the daylighted creek system. With the Rush Line BRT project having no immediate impact adjacent to the work within this Reach, this section of the channel could be constructed at a later date, when funding is secured and final design is complete.

Operations & Maintenance Ownership Opportunities Long-term there are several partnership opportunities that stand to benefit from the longevity and usefulness of this daylighting project. While we recognize that these partnerships will take time, we have identified some potential key stakeholders and opportunities for land acquisition in the current context.

Community Partners & Stakeholders • • • • • • •

Capitol Region Watershed District (CRWD) City of Saint Paul Lower Phalen Creek Project (LPCP) Metropolitan Transit – Rush Line Bus Rapid Transit Payne-Phalen District Council Ramsey County Ramsey Washington Metro Watershed District (RWMWD)

These partnerships would ultimately serve as a diverse network of stakeholders with an interest of preserving the creek and its long-term health and functionality. It is unclear how ownership would play into this equation and ultimately who would be responsible for the care, maintenance, and management of the daylighted creek corridor. Future collaboration will be required to determine these responsibilities.

Maintenance Operation and maintenance responsibilities would include, but are not limited to: • • • • •

Cleaning of stormwater BMP’s, pipes, structures, and channels (sediment removal, debris removal, erosion, and general repair) The maintenance of vegetated segments of the reaches Snow removal from trails Mowing and maintenance of adjacent turfed areas The repair and upkeep of trails, signage, lighting, and site amenities

A number of maintenance needs exist for the current condition, that would not significantly change under the proposed conditions. New maintenance needs associated with the daylighted channel and combined stormwater portions of the proposed conditions require collaboration that CRWD will facilitate.

Flower Power @ Phalen Creek: We Want it Back!

Event summary: Envision a future for the East Side where there's a creek brought back to the surface, a creek named for its relations with Dakota people and Dakota land, a creek respected and shared by the community.

On Saturday, September 5th, we got to do that with the incredibly talented artists of Flower Power and Oyate Hotanin as we celebrated the beautiful underground-waterway known to some as Phalen Creek. We gathered, created art where the creek once flowed, and experienced songs and spoken word while learning about this waterway that has since been altered, piped, and put underground.

So many folks who showed up have never heard about the creek or its violent history. But regardless of whether this was new information or not, we can proudly say that everyone we talked to wanted to be reunited with the mní (water) and see the creek daylighted and brought back! Wópida taŋka (many thanks) to everyone who made this day so special - what a wonderful gathering!

Highlight: Rendering of Restored Phalen Creek To help participants visualize the result of daylighting Phalen Creek, Capitol Region Watershed District generously produced and displayed a rendering of Phalen Creek, in which the creek flows above ground and community members interact with the creek and its surrounding amenities (benches, walking/biking paths, native plants, interpretive signs, and more). One popular feature was the depiction of public transportation. Many participants indicated their support for a more vibrant transit corridor in addition to a daylighted, multi-use creek area.

Many participants connected the rendering with the open field on which we placed our live flower installations and creek narrative signs. We found that children, in particular, were drawn to the rendering — throughout the day, we would see children walk up to the board and study the people using the daylighted creek; we would hear parents asking their children to point out the different uses depicted.

We found this to be another way to engage all community members — even those too young to fill out a survey!

Our event survey (with 35 responses as of 9/14/20) is summarized below:

Imniža Ska (the area we now know as Saint Paul) is Dakota land. The waterway of Phalen Creek once flowed four miles from Lake Phalen to Wakpá Táŋka (the Mississippi River). Dakota people relied on this waterway for travel to White Bear Lake and for culturally important foods like psiŋ (wild rice) found throughout the region. European-American colonization and rampant development contaminated this waterway, and by the early 20th century, Phalen Creek was buried underground in a concrete storm pipe.

With Flower Power @ Phalen Creek, we hoped to commemorate the relationship Dakota people have had with this waterway, discuss community efforts to bring Phalen Creek back to the surface, and restore its role as a connecting resource.

Answer the questions below to show this event impacted you. With your help, we can daylight this critical waterway!

Technical Memorandum To:

Melanie Kleiss, Lower Phalen Creek Project

From: Jonathon Kusa, PE and Ben Swanson, PhD, Inter-Fluve Project: Lower Phalen Creek Daylighting Feasibility Study Date: October 25, 2017

The Lower Phalen Creek Project (LCPC) retained Inter-fluve, Inc. (Inter-Fluve) to assess the feasibility of daylighting lower Phalen Creek, which is currently conveyed in storm sewer for much of its length between Lake Phalen and the Mississippi River. Based on available data and input from stakeholders, we identified two discrete reaches of Phalen Creek (Reaches 5 and 7) that are recommended for further investigation and analysis for potential daylighting.

Reach 4 is the stream segment within Swede Hollow, which is currently open channel, and is anticipated to be integrated into the daylighted system with future perennial baseflow. Some reconstruction of the Swede Hollow stream segment is anticipated, but not analyzed as a part of this feasibility study. The ultimate goal would be to daylight segments of the creek to restore ecological function, provide recreational and educational opportunities, and improve watershed health.

This memo summarizes the collected data and identifies potential reaches feasible for daylighting. The desktop analysis completed includes proposed stream profiles, alignments, and cross-sections; an opinion of estimated project costs by reach; and the general water quality benefits of daylighting streams. Field review and a more detailed engineering evaluation for each potential stream reaches is recommended.

Existing Conditions To assess the technical feasibility of daylighting lower Phalen Creek, Inter-Fluve collected available electronic spatial data from the City of Saint Paul (City), the Minnesota GeoSpatial Commons, the Capitol Region Watershed District (CRWD), and the Ramsey Washington Metro Watershed District (RWMWD). The data included the following: 

Transportation Network (roads, railroads, etc)



Geology (surface geology, bedrock geology, soils)

The data was compiled graphically and is summarized in the attached appendices. We have included a brief summary below of each appendix figure and the associated analysis.

Transportation Network –Appendix A The Phalen Creek corridor runs through an urban area crossed by city streets, highways, and a railroad. The three reaches proposed for daylighting will flow under 9 roads, 2 trails, and one set of railroad tracks. The proposed pipe will be buried under an additional 9 roads, 3 trails, and another set of railroad tracks.

Topography – Appendix B Local elevations range between 700ft and 900ft above mean sea, with a distinct upland between 850 and 900ft, moderately steep valleys along the I-35E and Phalen Boulevard corridors, and a relatively steep drop through riverside bluffs to the Mississippi River floodplain below. The Lower Phalen Creek corridor will likely begin at approximately 860ft elevation and end in a pipe at approximately 608ft. After emerging under a rise at Earl St, it will gradually steepen until it reaches Swedes Hollow, where it will fall 100ft to the floodplain downstream of I-94 (Figures 1 and 2).

Bedrock Geology– Appendix C Bedrock geology indicates potential historical stream alignment locations based on underlying bedrock indicators, includes location of exposed bedrock of various types and known stratification of the local geologic layers. In this area, locations that have eroded through the Platteville-Glenwood Limestone to the underlying Jordan Sandstone provide evidence of waterinfluenced erosion of the landscape, similar to what is visible in the Mississippi River gorge.

Surficial Geology – Appendix D Surficial geology provides evidence of more recent former locations of drainage paths through the landscape, based on more recent geological and climatic changes that influence the shallow surficial geology of the evaluated area. Several areas show evidence of Meltwater Stream Sediment within the surficial geology, providing evidence of former stream alignments.

Inter-Fluve, Inc.

ATTACHMENT D

Soil Types – Appendix E The lower Phalen Creek corridor begins above the Prairie Du Chien dolostone and turns west across the Jordan Sandstone and Platteville Limestone. It then spills back through Swede Hollow, which comprises Pleistocene stream sediments over more dolostone. Most of the rock is overlain by glacial meltwater sediments that form sandy loam soils. However, the soils are highly disturbed urban soils and often covered by fill and(or) impervious surfaces.

General Land Use – Appendix F and Tax Parcels – Appendix G Most of the area around Phalen Creek is residential, but the general corridor that includes the existing pipe and proposed alignment is primarily parkland or undeveloped property, with some industrial and commercial use. The proposed alignment is primarily in land designated as park or preserve, although some sections within proposed pipe reaches may be through undeveloped or industrial property. The proposed Phalen Creek alignment primarily flows through property currently controlled by Ramsey County and the City of Saint Paul.

Storm Water Sewer – Appendix H and Sanitary Sewer – Appendix I The storm and sanitary sewer systems cover the entire urban area within the Lower Phalen Creek corridor, and all the existing channel and tributary channels are conveyed within storm sewer. The Beltline Stormwater Interceptor is within the upstream end of the corridor, south of Lake Phalen. The Beltline Interceptor crosses the proposed channel alignment at Jessamine Ave. The Phalen Creek storm sewer runs along the proposed alignment for most of its length.

Water Table Elevations – Appendix J and Depth to Groundwater – Appendix K Between Phalen Lake and the Mississippi River, the water table elevation falls from around 860feet to 680 feet. Groundwater is close to ground surface around the lake and the river, but along the river bluff, south and east of the project area, depths to groundwater are often greater than 100 feet. Along Phalen Creek, depth to groundwater ranges between 0 and 35 feet below ground surface, and seeps in Swede Hollow are actually above ground surface.

Proposed Conditions Channel Alignment and Profile The topography, surface geology, landuse, parcel, and utility data through the lower Phalen Creek corridor, along with digital imagery, allowed for the development of an initial channel alignment describing the route and profile of a new, daylighted Phalen Creek channel (Figures 1 and 2). As described in the existing conditions section, the proposed channel will be a mix of

buried and open sections. Three potentially daylighted sections (Reaches 5 and 7) were determined based on adjacent landuse and infrastructure (i.e., width available for a channel and floodplain), as well as excavation volumes and their associated costs of removal. Proposed slopes range between 0.003ft/ft to 0.025ft/ft. Steeper sections will likely require larger bed and bank materials to account for higher energy flows. See Table 1 for a summary of evaluated technical elements.

Based on experience with similar projects, Inter-Fluve recommends constructing a diversion structure at the outlet of Lake Phalen, which would allow for control of water entering the proposed daylighted segment of Phalen Creek. Utilizing a diversion, the system will be “offline” from the existing stormwater system and designed to have consistent base-flow that fluctuates within a narrow range. The proposed system will supplement the existing storm sewer network and not replace the conveyance capacity currently available. As an “off-line” channel, the proposed stream can be designed as a typical spring-fed stream, which have small channel widths and minimal floodplains. The limited scale of the proposed system will be required given the limited area available in some segments.

Channel Cross-Section An initial channel cross-section was designed as a trapezoid channel with a bottom width of 4feet, side slopes of 4:1 (horizontal:vertical), and channel depths equal to excavation from existing ground surfaces. At a design flow depth of 2 feet, the proposed channel could pass flows from 50cfs to 314cfs, at slopes from 0.003ft/ft to 0.1ft/ft, respectively (Appendix L). If a bypass is designed for approximately 1 cfs, which is a reasonable flow to maintain ecological integrity of the stream, the proposed channel dimensions will allow for vegetation, large wood, and other flow restricting habitat features. It would also allow for encroachment in some areas for public access and bridge crossings.

The side slope can be flattened depending on space and aesthetic desires. Additionally, a floodplain bench (10-foot minimum) is desired where space allows. The bench provides an area for important soil and vegetation interactions with floodwater and runoff, as well as space for storing water during high flows. Although desired, adding a floodplain will not be critical since the proposed flow diversion will reduce the “flashiness” of storm runoff to the channel.

Recommendations Based on available data, Inter-Fluve recommends three discrete reaches of Phalen Creek, Reaches 5 and 7, for further investigation and analysis for potential daylighting. The following section provides a brief description of each recommended daylighting reach.

Reach 7 This reach was selected based on proximity to the water source, depth of excavation, and land ownership. First, the segment is located at the upper reach and could be constructed as a “stand-alone” segment of the system. The proposed reach would include reconstruction of the lake outlets to allow for a diversion of base-flow into the proposed stream channel under East Shore Drive or Wheelock Parkway. At the terminal point of Reach 7, the water would be diverted back into the Beltline Sewer system (estimated channel invert = 851.5ft, estimated Beltline Sewer Invert = 847.7ft). The area is City-owned park space, which may be more accessible for a stream construction project. The Reach would require relatively shallow excavation depths (approximately 6 feet) to construct the channel.

Reach 5 This reach was selected based on relatively shallow required excavation depths, available public and private undeveloped land, and localized stormwater discharge capture potential. Reach 5 generally requires excavation between 3 and 11 feet vertically to achieve proposed channel grades. While each of the nine subreaches has unique impacts to properties, they generally lie within either publically owned greenspace or undeveloped privately owned parcels. To achieve consistent base-flow, Reach 5 would require construction of approximately 4,300 linear feet of 12 –inch sewer pipe to convey water from Reach 7. However, Reach 5 does have an estimated three local stormwater sewershed basins that discharge towards the proposed creek alignment. A portion of the flow from these sewersheds could be redirected to the proposed stream to create an ephemeral stream flow, in the absence of perennial flow from Lake Phalen.

In addition, the sewersheds could be treated within new BMPs, which could be constructed as a part of the project.

Channel Excavation Along the two proposed daylighting sections, expected excavation depths range from 2- to 11feet, with average depths of excavation between 3 feet and 7 feet (Table 1). Excavation volumes were calculated using the area defined by the design cross-section with the average excavation depth at each section of each reach and the length of each section. Excavation volume estimates for each proposed reach are provided below (Table 2).

Table 2. Estimated channel dimensions and excavation volumes for proposed reaches.

Opinion of Probable Project Costs The opinion of probable daylighted channel costs are based on the initial excavation volume estimates (Table 1) compounded by typical infrastructure, landscaping, and survey /engineering/permitting/design costs as a percentage of the estimated earthwork cost. The analysis completed meets Class 5 criteria per the American Association of Cost Engineers (AACE) International standards; consequently, the costs could vary between -50% to +100% from the values provided. Based on our experience providing similar estimates, Inter-Fluve recommends and has applied a 50% cost contingency for each proposed project reach.

In addition to providing the total opinion of probable construction cost estimate for each reach, we have calculated the cost per linear foot, since the length of each reach varies. The cost per linear foot can be used as a rough metric for cost/benefit comparison between reaches.

Our

complete opinion of probable project costs for each reach is provided in Table 3.

Inter-Fluve, Inc.

ATTACHMENT D

Lower Phalen Creek Daylighting Feasibility Study

In addition to the elements provided in the OPC, several other potential large project costs should be considered: 

Reach 6 Pipe: Approximately 4,300 LF of pipe is required to convey flow from Reach 7 to Reach 5 if a perennial stream is desired within the lower reaches. For conceptual cost purposes, the design team has assumed 15” round concrete pipe (RCP) will be installed, which has adequate capacity to convey the desired 1 cfs flow at the anticipated 0.1% slope. The estimated ballpark cost with a 50% contingency and accounting for engineering fees for this project element is $425,000. This estimate does not include any required property or construction easements.



Lake Phalen Outlet Reconstruction: To divert consistent base-flow from the Beltline sewer to the proposed daylighted Phalen Creek, the existing outlet structures from the lake would need to be reconstructed. The outlet reconstruction would require engineering analysis, hydrodynamic stormwater modeling, structural engineering, and construction. A ballpark estimate for this project cost is $400,000, based on engineering judgment accounting for the complexity of the design and site logistics.

Lower Phalen Creek Daylighting Feasibility Study

Water Quality Assessment Numerous studies have focused on the impacts of stream daylighting on fish habitat (e.g.

Pinkham 2000; Jones 2001), or the sociological, aesthetic, or economic reasons for daylighting (e.g. Pinkham 2000; Jones 2001; Shin and Lee 2006; Buchholz and Younos 2007; Sinclair 2012).

Daylighting buried streams may foster a number of social, economic, and ecologic improvements, including, but not limited to, the following: 1. Relieve flooding issues by reducing “pinch” points at under-sized culverts and providing greater flow capacity by recreating a floodplain along the channel.

2. Reduce runoff velocities by increasing roughness and water storage/attenuation.

3. Improve water quality by exposing water to air, sunlight, vegetation, and soil 4. Recreate aquatic and riparian habitat and improve wildlife passage 5. Provide recreational, leisure, and(or) educational amenities 6. Beautify neighborhoods, attracting residents and visitors and possibly contributing to greater civic pride (Pinkham, 2000; Wilde et al. 2011).

In natural, open channels, sunlight and biological production play important roles in controlling normal levels of nutrients and even some pollutants. On its own, sunlight breaks down organic compounds to more biologically useful forms. Sunlight also provides the energy required for algae and other plant production, which in turn, drives the productivity and diversity of bacteria and grazer species that help use and breakdown nutrients and metals in the water. Natural, open streams also generally flow through a variety of stream side environments, resulting in heterogeneous channel forms and processes driven by varying bed materials (e.g., sand, gravel, wood), bed forms (e.g, pools and riffles), groundwater-surface water interactions, and floodplain-channel interactions. This physical channel heterogeneity generally increases residence times, connectivity, and transient storage of both water and sediment along the channel. Placing streams in underground pipes limits these ecological processes along the impacted reach, thereby reducing conditions conducive for supporting anticipated levels of bioproductivity and biodiversity; nutrient retention, uptake, and processing (e.g., denitrification); ecosystem metabolism and food web dynamics; and others (Pennino, et al 2010;Figure 3).

Restoration of open, channelized streams increases nitrogen use by plants and animals, storage in sediment (Bukaveckas 2007; Klocker et al. 2009) and denitrification (Kaushal et al. 2008b; Harrison et al. 2011), and enhances carbon processing (Lepori et al. 2005; Sivirichi et al. 2011).

Few studies, however, have measured the direct effects of daylighting on stream biogeochemistry. Daylighting a buried stream drastically transforms the system, and opening the system to light and more natural channel conditions, likely dramatically improves Inter-Fluve, Inc.

biogeochemical processing. Added heterogeneity, especially if built into a restoration plan that includes riffles, pools, eddies, pocket water, etc. will add habitat for a range of fish, macroinvertebrates, and others, as well as provide areas for sediment and water retention and local groundwater-surface water interaction (i.e., hyporheic exchange). The few studies that have examined the impact of daylighting streams found decreases in fecal coliform levels and increasing taxa richness, (Charbonneau and Resh, 1992), and(or) a change in invertebrate composition from bioďŹ lm feeding collector-browser communities to algal grazer communities (Neale and Moffat 2016). Pennino, et al. (2010) reported stream burial reduced nitrate uptake rates by a factor of 8 and general primary production by a factor of 11 along impacted reaches of Maryland streams, and indicated that daylighting could alter these systems to improve both carbon and nitrogen processing.

Site work is complete, and the site is in a state of long-term temporary stabilization, pending redevelopment plans.

No surety was required for this public project.

Ms. Hosch explained that the project has been complete for some time, but construction materials were being stored on site and have now been removed for the permit to be closed out.

Stormwater is treated via one underground iron enhanced sand filtration system.

The site is stable, and the stormwater treatment system has been confirmed to be functional. There is a $13,500 surety to return.

Motion 20-242: Approve $13,500 surety return and approve Certificate of Completion for permit #17022 Regions Birth Center.

Murphy/Sanders Unanimously Approved C) 18-003 Marydale Park – Closure (Martinkosky) Mr. Martinkosky reviewed permit #18-003 for Marydale Park – Closure.

The applicant, 1825 University Limited Partnership will remove all existing structures. The applicable rules are Stormwater Management (Rule C), Flood Control (Rule D), and Erosion and Sediment Control (Rule F). The disturbed area of this project is 3.2 acres with 2.58 acres impervious surface.

Motion 20-245: Approve with 4 Conditions Conditions: 1. Receipt of additional $1,900 surety. Total surety of $12,900 is due based on impervious area in plans dated 12/2/20. $11,000 surety check has already been received by the CRWD. 2.

On July 10, 2006, the Board of Managers established a Capital Improvement Fund to finance current and future capital improvements and transferred $2,402,169 from the General Operating Fund to the Capital Improvement Fund.

In early December 2017, CRWD’s Board of Managers approved the budget and financing plan for the 595 Aldine Renovation Project and adopted a reimbursement resolution providing for the reimbursement of capital improvement funds from sale of $10,000,000 general obligation bonds. On January 17, 2018, CRWD Board of Managers authorized $10,000,000 in general obligation (GO) bonds to be sold for improvements to the 595 Aldine property.

On November 18, 2020, CRWD has certified completion of the 595 Aldine Office Renovation Project and made final payments. The District incurred costs for the project prior to the issuance of bonds and the Board of Managers had previously issued a reimbursement resolution to utilize bonds funds to reimburse Capitol Funds used for property acquisition and design services.

As of November 30, 2020, $2,012,750.59 remains in the bond fund and should now be transferred to the Capitol Improvement as a reimbursement for costs incurred prior to issuance of bonds.

Motion 20-249: Adopt Resolution authorizing the transfer $2,012,750.59 and any additional interest from the Bond/Building Fund to the Capital Improvement Fund.

Murphy/Sanders Unanimously approved D) AR: Approve 2021 Partner Grants (Schwantes) Ms. Schwantes reviewed that the Board approved distribution of the 2021 Partner Grant Request for Proposals at the September 2 meeting. A virtual workshop was held on October 7 for 28 prospective grantees to discuss the application and contracting process and for staff to present program priorities with the goal of receiving stronger proposals. Applicants were asked to address how COVID-19 restrictions would impact the execution of their proposal and proposals serving communities in CRWD’s identified key watersheds of Trout Brook, Phalen Creek, Saint Anthony Hill, Como Lake or Lake McCarrons would receive additional consideration.

Proposals for 2021 Partner Grants were due November 1. CRWD received 26 applications totaling $330,758. The 2021 Partner Grants budget is $135,000. On November 30, the Partner Grant Review Committee consisting of President Collins, Manager Murphy and CAC members David Arbeit and Mary Lilly reviewed the applications and staff recommendation and agreed on the proposed funding recommendation.

The Committee developed recommendations totaling $140,500 for 18 proposals or $5,500 over the 2021 budget for the program. Staff request the Board amend the 2021 Partner Grant Program budget to support the projects and programs recommended by the Committee.

The Committee continued to discuss how to review proposals and support grantees that have received funding for several consecutive years as well as new partnerships. A meeting with program staff and the 2021 Partner Grant Review Committee will be scheduled for early 2021 to discuss program improvements including budgeting and the review process.

Motion 20-250: Approve 2021 Partner Grant funding and amended program budget and authorize the Administrator to enter into grant agreements with the applicants.

Murphy/Sanders Unanimously approved E) AR: Approve MN Stormwater Research Council Contribution (Fossum) Mr. Fossum reviewed that over the past three years, the Managers have approved an annual $25,000 contribution to the MN Stormwater Research Council. This money along with funding from other organizations has totaled $325,000 and has funded twenty projects. This level of effort would not be possible without the collective approach being implemented.

Funding for Research has been included in CRWD’s Budget and Workplan in each year from 2014—2020.

Multiple small-scale research projects have been funded and completed by District staff as well as through partnerships with local research institutions.

Since 2017, CRWD has contributed to the MN Stormwater Research Council to jointly fund applied stormwater research. Staff will review the projects currently underway and request contribution for the next round of funding that is currently being solicited.

Fiscal Note: 2020 Budget for 228-20330 District Research Program is $50,850.

Motion 20-251: Approve contribution for the MN Stormwater Research Council for $25,000.

Murphy/Sanders Unanimously approved F) AR: Approve Amendment with Barr Engineering for Seminary Pond Improvement Project (Eleria) Ms. Eleria reviewed that in late September 2020, CRWD’s Board of Managers issued a notice of award to Nadeau Companies for construction of the Seminary Pond Improvement Project. Design engineering and construction management services has been provided by Barr Engineering.

In June 2020, the Board approved an agreement amendment for Barr Engineering in the amount of $73,200 for bidding, permitting and construction management services. Since June, CRWD’s Administrator has approved two additional amendments to Barr’s agreement for the following work: 1) additional support on wetland permitting, easement and agreement development and bidding and 2) design services for interpretive signage. The amendment amounts are $11,490 and $6,535, respectively.

Ms. Eleria shared that with over 60% of construction completed as of this date, CRWD and Barr Engineering anticipate the need for additional budget for surveying and construction administration and observation (C&A). Originally, it was assumed that the contractor would conduct surveying, however based on their method of surveying and staking, it was determined that Barr should conduct survey work. A total of three survey visits are needed totaling $5,240. In addition, it was assumed back in June

that active construction would last eight weeks, and Barr’s C&A budget reflected this timeframe.

However, active construction is anticipated to extend an additional 4-6 weeks due to weather conditions and delay in receiving the easement for east outfall work. Additional C&A services may cost up to $19,980. In total, the additional scope of work for Barr is estimated to cost $25,220.

Motion 20-252: Approve an agreement amendment with Barr Engineering for construction management services for the Seminary Pond Improvement Project in an amount not to exceed $25,220.

Murphy/Sanders Unanimously approved G) AR: Adopt Final 2021 Budget and Levy (Doneux) Administrator Doneux reviewed that each year the Board of Managers must establish a plan of work for the upcoming year, establish a budget based upon the work plan and establish a levy for the budget. The Board of Managers discussed the current 2020 budget and revenue at the May 6th and 21st Board meetings. The Board also reviewed the preliminary 2021 Work Plan along with the budget and levy at Board workshops on June 3rd and July 8th as well as at Board Meetings on June 17th and July 22nd, 2020. The Citizen Advisory Committee reviewed and recommended approval on the proposed 2021 budget and levy at their August 12th meeting. A duly noticed Public Hearing was held on August 19th to collect public comment on the proposed 2021 budget and levy. The District did not receive any comments as of August 27th. The Board of Managers adopted a Preliminary 2021 Budget and Levy Certification on September 2, 2020.

Administrator Doneux recommended that the Board adopt the final budget and levy as presented. The final budget of $799,100 for Administration, $3,626,434 for Programs, $942,786 for Projects for a total Operations Budget of $5,368,320 and $4,035,744 for Capital Improvement Projects. This results in a total Final 2021 Budget of $9,404,064. This is a decrease of $2,388,419 from the adopted budget for 2020 but a 3.8% increase from the preliminary 2021 budget. Staff will review these minor changes with the Board at the meeting. The proposed 2021 tax levy is $8,277,699. This includes $7,223,245 for the operations and capital improvement levy and $1,054,454 for debt. This levy is the same as 2020.

Motion 20-253: Adopt the Resolution approving the Final 2021 Budget and Levy and direct Board Treasurer and Administrator to certify the 2021 Property Tax Levy with Ramsey County.

January 6, 2021 Board Meeting VI. Unfinished Business - A) 595 Aldine Office Renovation Project Recap (Doneux)

DATE: TO: FROM: RE:

September 26, 2019 CRWD Board of Managers Mark Doneux, Administrator 595 Aldine Office Renovation Project Recap

Background In 2012, CRWD embarked on an effort to locate a new, long term office space. Our previous 8,600 square foot lease space lacked adequate staff space, storage, equipment operations had no room for further growth and had no outreach opportunities. In 2016, the District entered into a purchase agreement for the 15,000 square foot former McQueen Equipment building. Design took place in 2017 and construction was substantially completed in December 2018.

This project was a complete building renovation from a former heavy equipment sales and repair business to a modern office space. The project is also be a brownfield redevelopment due to impacted soils, solvent vapors beneath the slab as well as lead and asbestos inside the building. At the November 18, 2020 Board meeting, the Board of Managers authorized the final payment to JE Dunn, our building contractor. On December 16, 2020, the Board authorized a fund transfer of the remaining bond proceeds to be transferred back to the District’s CIP Fund as a reimbursement for outlays prior to the 2018 bond sale. These final official steps close the chapter of the planning, design and construction phase of the 595 Aldine Renovation Project.

Issues While the District moved into the 595 Aldine building on December 3, 2018, the last two years have been a transition from construction punch lists to the new world of building management. I believe it is important that District know its past and the journey of this building project. This project lasted eight years from the start of planning in 2012 to last month’s project close out, and cost $11.5 million dollars.

I will give the Board a presentation that will recap the journey of planning, designing and building the office space. In the presentation, I will also highlight the next steps to make this building fully meet its outreach and service functions. Later this winter, I will convert the presentation into a report format that will serve a reference document on this building project.
